VLT AQUA 12-Pulse High Power Instruction Manual
Starts/stops the lead pump (controlled by
the adjustable frequency drive). A start
requires that also a System Start signal has
been applied, e.g., to one of the digital
inputs set for Start [8]!
Forces alternation of the lead pump in a
cascade controller. Lead Pump Alternation,
25-50 Lead Pump Alternation must be set to
either At Command [2] or At Staging or At
Command [3]. Alternation Event,
25-51 Alternation Event can be set to any of
the four options.
The function will depend on the setting in
25-06 Number Of Pumps. If set to No [0],
then Pump1 refers to the pump controlled
by relay RELAY1 etc. If set to Yes [1], Pump1
refers to the pump controlled by the
adjustable frequency drive only (without
any of the built-in relays involved) and
Pump2 to the pump controlled by the relay
RELAY1. Variable speed pump (lead) cannot
be interlocked in the basic cascade
controller.
